No problem :-)

So, I took a look at this today. It was actually pretty easy to add
support for this to config, and my local version now generates option
headers. I have a couple more things to tweak, but I plan on comitting
this Very Soon (next couple of days, probably).
Oh, I should mention that I wrote it so that options can be turned
in to "option header options" one at a time, so that we don't have
to convert the whole source tree at once :-)
